10. A painter is rotating a telescopic painting pole clockwise about its end. Initially the pole is 1.5 m long, has a mass of 1 kg, and is rotating at w = 6 rad/s. If the rotational inertia of a rod rotating about its centre of mass is given by Icm = ML/12, (a) use the parallel axis theorem to find the moment of inertia of the painting pole rotating about its end. (b) Calculate the rotational kinetic energy of the rod. (c) Calculate the rods angular momentum. Use a sketch to denote the direction of the angular momentum vector. (d) If the telescopic pole extends to 3 m, find the new angular velocity of the painting pole.
